Abstract (en)

[origin: US4403077A] The invention relates to novolak oxyalkylate mixed esters which, on the one hand, contain benzoyl and/or naphthoyl radicals and, on the other hand, contain maleic acid and/or sulfosuccinic acid half-ester groups. They are obtained by reacting novolak oxyalkylates with benzoic acid and/or naphthoic acid or with its anhydride or chloride on the one hand and maleic anhydride on the other hand and, if appropriate, reacting the maleic acid half-ester groups with sulfites to give sulfosuccinic acid half-ester groups. These compounds are highly suitable for use as dispersing agents for the preparation of low-foam dispersions of pigments, dyestuffs and other agents and as emulsifying, leveling and dyeing auxiliaries.
